Banana Custard

Banana custard is a banana pastry cream, a thick and rich custard that works as a filling, a topping or a dessert on its own.

This homemade version is described as superior to instant pudding mix because the banana flavor comes from infusing milk with real bananas rather than from banana flavoring or banana extract.

That single step is what makes the finished custard taste like fruit instead of like candy.

The same recipe fills cupcakes, cakes, pies, tarts and macarons, fills choux puffs, builds banana pudding, and can simply be eaten by the spoonful. It is also the custard used for Banana Creme Brulee Cupcakes and Banana Pudding Cups.

One batch yields 1.25 cups. The active work is quick, about 20 minutes of prep and 5 minutes of cooking.

The waiting is where the flavor develops, with at least 1 hour of resting time while the bananas infuse the milk, and the custard then needs to chill completely before you use it.

Because of that, it is an easy make ahead component for a dessert you plan to assemble later. This recipe is adapted from the original banana custard recipe from Pies and Tacos.

Banana Custard Ingredients

You will need a short list of everyday ingredients. Whole milk and very ripe bananas carry the flavor, while egg yolks, sugar and cornstarch give the custard its body and its ability to set.

2 cups milk (480 ml)
2 cups very ripe chopped bananas (340 g, about 3 to 4 medium bananas)
1 vanilla bean, split in half (optional)
4 large egg yolks
1/2 cup granulated sugar (100 g)
3 tbsp cornstarch (24 g)
1/4 tsp fine sea salt
1 tbsp unsalted butter, at room temperature (14 g)
1 tsp vanilla extract (optional)

Both vanilla options are flexible. You can use a split vanilla bean in the infusion, or skip the bean and stir vanilla extract in at the end, off the heat. Either way you get a glossy custard with a clear banana flavor, and either way the butter goes in last for richness and shine.

How to make banana custard

The method is simple, but two moments decide whether the custard turns out silky or scrambled. The first is the infusion, where the bananas flavor the milk. The second is tempering, where the hot milk meets the egg yolks. Read through the steps once before you start, and keep your whisk and a spatula within reach.

Place the milk, sliced bananas and the seeds from the vanilla bean, if you are using one, in a small saucepan over medium heat and bring it to almost a boil.
When you see the first few bubbles, remove the pan from the heat. Cover the pan and let the bananas and milk infuse for at least 1 hour, or place the pan in the fridge overnight. This is what enhances the banana taste.
When the milk is done infusing, place the pan back over medium heat and reheat until hot.
While the milk reheats, whisk together the egg yolks, granulated sugar, cornstarch and salt in a bowl and set it aside. Whisk until the mixture reaches a ribbon consistency, so it flows off the whisk in a thin ribbon.
Strain the hot milk, being careful so you do not let any banana pieces get through the strainer. Gently squeeze the bananas to release as much milk as possible from the solids without letting them through.
You can use this banana pulp to make cupcakes or cakes, or any recipe that calls for mashed bananas. Or discard it.
Slowly pour 2 tablespoons (30 ml) of the hot milk over the yolk mixture while whisking nonstop. Keep adding the remaining milk very slowly, whisking the custard continuously.
Once all the milk has been added to the yolks, return the whole mixture to the saucepan that you used to heat the milk. Pour it through a fine mesh sieve to remove any bits of yolk that may have cooked or banana pieces that may have gone through.
Place the pan over medium heat and cook, stirring nonstop with a wooden spoon or spatula, making sure to scrape the sides and bottom very well while you cook.
The custard will start to get thick and it will look lumpy for a while. Keep stirring over medium heat. After a minute or so, the mixture should be thick and smooth, and it should coat the back of a spatula in a thick layer.
Remove the pan from the heat and add the butter, and the vanilla extract if you are using it, stirring to combine. Pour the custard into a small bowl and cover it with plastic wrap placed right on the surface so it does not form a skin as it cools. Place it in the fridge to chill completely.
Use the chilled custard to fill cakes, top cupcakes such as Banana Creme Brulee Cupcakes, fill pies, or make Banana Pudding or Banana Pudding Cups.

A few details matter while the custard cooks. The mixture will look lumpy before it looks smooth, and that is normal. Keep the spatula moving and scrape the bottom and sides of the pan, because that is where the custard catches first.

If the mixture starts to bubble hard, lift the pan off the heat for a moment and lower the flame. Once the butter goes in, the custard turns glossy and the texture evens out.

Pour the hot milk over the yolk mixture very slowly while whisking nonstop so the eggs do not scramble, then return everything to the pan and cook over medium heat until the custard gets thick and smooth.

Tips for making Banana Custard

These details make the difference between a custard that sets up beautifully and one that turns grainy or tastes flat.

Use super ripe bananas. The riper the fruit, the more banana flavor moves into the milk.
Infuse the bananas with the milk for at least 1 hour, or leave the pan in the fridge overnight. Longer infusion gives a stronger banana taste.
If you are not using a vanilla bean, add 1 teaspoon more vanilla extract at the end, after the custard is off the heat.
Strain carefully so very little banana passes through. Banana pieces can make the custard chunky and give it a green color.
Add the milk slowly when tempering so the eggs do not cook or scramble.
Stir the custard the whole time and do not let it boil.
The custard may seem curdled at first, but it thickens and becomes smooth as it cooks.
Keep the heat at medium, or a little lower if your pan runs hot, so the eggs stay smooth.
The pudding thickens more as it chills in the fridge, so judge the final texture after chilling rather than straight from the pan.

The vanilla is the one place where the recipe gives you a choice. A split vanilla bean infuses alongside the bananas and adds a soft background note. Vanilla extract, added after cooking, keeps the custard bright and lets the banana lead. If you skip the bean, plan on 1 teaspoon of extract at the end.

Timing is worth planning around. The infusion needs at least an hour at room temperature, and the custard then needs to chill completely, so this is a component to make in the morning or the day before rather than in the last ten minutes before serving.

Covered and chilled, it holds its smooth texture and its banana flavor, and it is ready to pipe when you are.

What to use Banana Custard for

This banana pastry cream is thick enough to pipe and it holds its shape well, which makes it a flexible filling and topping rather than a loose sauce.

Banana pudding, or individual Banana Pudding Cups.
Filling and topping for Banana Creme Brulee Cupcakes, torching the top after piping.
Banana Raspberry Pie. Make 1.5 times the recipe so you have enough to fill the whole pie.
Banana Macarons, paired with a whipped ganache.
Choux puffs, cakes or tarts.
Eaten with a spoon like a regular pudding.

If you enjoy banana desserts, this custard sits comfortably next to other favorites. A banana cream pie recipe relies on a similar custard filling, while a banana pudding bars recipe turns the same flavors into a layered, sliceable treat.

Banana Custard, What to use Banana Custard for

For a wider look at banana custard for cakes and layered desserts, that guide covers several classic variations you can build on.

The 1.5 times note for Banana Raspberry Pie is worth remembering, since one batch of 1.25 cups is sized for cupcakes, macarons and small tarts rather than a full pie shell. Scale up before you start cooking so you are not short at assembly time.

The source also lists other recipes worth trying once you are comfortable with this method: Banoffee Bars, Banoffee Cake, Passionfruit Curd, Pistachio Paste and Lemon Curd. Each one uses the same patient approach, building flavor slowly and then cooking gently so the result stays smooth.

Because the custard is thick and stable, it also works as a make ahead layer in trifles and parfaits, and it can be spooned over sliced bananas for a very quick dessert. However you use it, keep it covered and chilled until the moment you serve it.

FAQs

How do you make banana custard from scratch?

To make banana custard from scratch, you infuse milk with ripe bananas and vanilla bean, then temper egg yolks with the strained milk and cook the mixture with cornstarch until thick. The process takes about 20 minutes of active prep, 5 minutes of cooking, and at least 1 hour for the milk to infuse. Once cooked, stir in butter and chill the custard completely before using.

Why does my banana custard get lumpy?

Banana custard can become lumpy if the hot milk is added too quickly to the egg yolks, scrambling them, or if the heat is too high during cooking. To prevent lumps, slowly pour the hot milk into the yolks while whisking constantly and cook over medium heat while stirring nonstop. If lumps do appear, remove the pan from heat immediately and whisk vigorously, or strain the finished custard through a fine-mesh sieve.

What is the difference between banana custard and banana pudding?

Banana custard, also called banana pastry cream, is a thick, silky, starch-thickened stirred custard made with egg yolks, milk, sugar, and cornstarch. Banana pudding is a layered dessert that typically combines banana custard with vanilla wafers and whipped cream or meringue. The custard itself serves as the creamy base for the pudding, but the terms are often used interchangeably in home cooking.

How long does banana custard last in the fridge?

Banana custard will maintain peak quality for about 3 to 4 days when stored properly in the refrigerator. It must be covered directly with plastic wrap placed on the surface of the custard to prevent a skin from forming. Banana custard does not freeze well, as the starch gel will break upon thawing and result in a watery consistency.
